A Firefox install is amzingly simple -- copies everything from IE automatically. I also installed Thuderbird, which was just as easy, it copied everything from my Eudora account.

I use the free, sponsored mode, which puts one tiny ad in a box in a corner of the software, which I don't even notice.

Not sure how that happened if his router was set up properly. Each computer on the network, even a stranger sitting outside with a laptop, should go directly to the wireless router and then to the DSL modem, and should not even be aware there is another computer on the network. Your computer sitting inside the house should not be aware that someone outside is using your network. The DSL is fast enough that it might take 15 or 20 or more folks lined up outside your house like birds on a power line before the service would lag a little.
I have my router set up with the hardware firewall and have Norton, etc. on my computer, and do not enable file sharing, but I do NOT have any security on my router. I really don't give a hoot if someone else is using my cable internet connection, it doesn't bother me. Right after last Fall's hurricanes, my insurance adjuster sat out in the driveway for about 20 minutes before coming to the door. When he did knock on the door, he thanked me for the use of the connection because the hotel where he was staying only had dial-up, and he had to file several reports. It was no skin off my nose...
